On an HP 5820-24XG-SFP+ (JC102A) the ports cabled with genuine HP X240 10G SFP+ 3 m DACs (JD097C) came up but logged OPTMOD/4/FIBERSFPMODULENOWINVALID: This is not a supported transceiver for this platform, and broadcast/multicast counters on those ports grew faster than normal. The cable is listed…
The poster configured new HP 2530-48G switches (J9281B) with J9775A SFP+ direct-attach cables bought as accessories. The ports stayed down and the log said FFI: port 49 Transceiver type not supported in this port; show tech transceivers first showed nothing and, after upgrading from YA.15.12.0007…
A 2920-48G-PoE+ (J9729A) rejected a J9283B 3 m SFP+ DAC with 00536 FFI: port 45 Transceiver type not supported in this port even though HP lists the cable as compatible; the same cable worked in a 2530 with SFP+ slots. Firmware had been updated without effect. A later reader noticed an old J9283B…
On an HP 5120-EI the poster inserted an Allied Telesis AT-SPEX 1310 nm SFP and got a PHONY ENTITY trap plus OPTMOD/4/FIBERSFPMODULENOWINVALID: This is not a supported transceiver for this platform; the port never came up. The poster looked for a command to disable enforcement of SFP coding. Later…
Four HP A5500-HI switches in an IRF stack logged unsupported transceiver messages for six rear-module (JD368B) ports that were cabled with HP J9281B SFP+ DACs to ProLiant Gen8 servers with 530SFP+ NICs. display transceiver interface showed Transceiver Type STACKSFPPLUS, Connector COPPER, Vendor…
Across about forty ProCurve/Aruba switches the poster had used J4858C and J4858D 1G SX SFPs without issues, but eight newly purchased J4858D units logged Unsupported Transceiver on 2530-8G (J9774A, YA.15.16.0006), 2530-8G (J9777A, YA.15.12.0007) and 2530-24G (J9776A, YA.15.10.0003). show tech…
Four HP ProCurve 6120XG blade switches (516733-B21) refused J9150A 10G SR SFP+ transceivers that the datasheet lists as supported; show tech transceivers reported them as unsupported. The switches ran Z.14.56. The poster asked whether a firmware upgrade or a configuration setting was needed…
The poster operated old HP/H3C A5800 switches (JC100A, JC103A) with many SFP modules of mixed coding. Modules with H3C in A0h bytes 60h-62h worked but logged This is not a supported transceiver for this platform, and DDM plus serial/date information were unavailable. Copying the full data from a…
The poster needed to connect a MikroTik CRS328-4C-20S-4S+RM to an HP 1820-24G-PoE+ over 200-500 m of outdoor aerial fibre and asked which SFP modules to buy and how to verify compatibility before purchase. The HP compatibility table listed only J4859C as a single-mode SFP, while MikroTik offered…
The poster wanted a cheap 10G link between servers with Intel X520-DA2 NICs and an HP switch and worried that a direct-attach cable is coded either for Intel or for HP but not both. A respondent shared that two X520-DA2 cards would not link directly over a DAC in their case, but a Dell DAC…
